حاضر سازد؛ و ما ائمّه معصومین هفتاد و دو حرف از آن را میدانیم. یک حرف را هم خداوند به خودش اختصاص داده و تنها نزد اوست" "The Almighty's greatest name has 73 letters (or parts). Asif ibn Barakhia knew only one letter of it, which enabled him to traverse the earth in the blink of an eye. We Shia Imams however possess 72 of them. And the last letter is concealed from all creation and remains a secret to only the Almighty Himself." Being an allegedly esoteric knowledge by nature, it is not known exactly how it takes place, but theories and explanations abound. The most prevalent theory has to do with the concept of consciousness and will (اراده). The person wills to be some place, and he is then simply there an instant later. This view can perhaps be understood from the perspective of Western philosophical idealism, where esse est percipi: if space does not have an objective reality, and reality itself is thought of as observer-based and a subjective entity, then ideas such as moving in space without actually physically moving are no longer uncharted possibilities. In addition, the jinn are believed to possess this knowledge of transportation, however in a limited amount, as is evident again from the aforementioned Quranic verses. History Famous Sheikhs, Imams, and prominent figures in Islam, such as Abusaeid Abolkheir or Rumi or Al-Khidr, were believed to possess keramat, and writings from medieval Islam are full of stories and reports of certain individuals possessing such a trait. For example, Idries Shah and Robert Graves mention the case where senior members of the Azimia order were "reputed to appear, like many of the ancient Sheikhs at different places at one and the same time". Many other examples can be found in Attar's Tadhkirat al-Awliya (Biographies of the Saints) or the works of Ibn Arabi, as well as other similar chronicles. However, no one for sure has known the number and identity of all those who possess such knowledge, since according to Hujviri, those who hold such knowledge "do not know one another, and are not aware of the other's state of excellence, and are hidden from themselves and from mankind." One of the most discussed phenomena of this supposedly esoteric knowledge is the event of traveling without actually moving (طی الارض). Islamic texts and records (from the mystics) are full of such accounts
